This invention relates to an improvement in toilet seats for the purposeof lowering their cost, improve their quality, facilitate the cleaningof the bowl, obtaining the advantage of covering the hinge ixturewithCelluloid, a neater appearance and stronger construction.

In accordance with the common practice, toilet seats are of dierentshapes and materials, some are equipped with a lid; this type is bestadapted to homes; some are without lid, which are mostly in use inschools, hotels, office and public buildings, but all these types areequipped with metal hinges which are always exposed to view; it isthere- Vfore necessary to cover them always with some iinish so as togive them a neat appearance. In some cases they are finished in Duco andin others with vulcanized rubber, but the majority of all the diferenttypes today in use, are either nickel or chromium plated.

Some types of hinges are provided with an offset, but all types oftoilet seats equipped l with said hinge xtures as customarilyconstructed and used, have several disadvantages, namely: n

The Duco inish is a long and expensive process, Yand which with usediscolors .and chipseasily. Y v

The vulcanizing process is also a long and expensive one, and the choiceof color is limited to black. This prevents the hinges matching whatevercolor` the seat is covered '5 with.

The nickeland chromium finishes become oxidized for obvious reasons,therefore it is necessary to polish them daily, and this plating processis also expensive.

In hotels, where hundreds, and in some cases thousands of toilet seatsare installed the upkeep is very expensive, considering the polishingmaterial and labor entailed.

v rihe hinges without an offset have the inliconvenience of bringing theseat, whether in a raised or a lowered position, very close to the bowl,thus rendering the cleaning of the rear top thereof, difficult.

V None of the types ofhinges at present in n use, can be covered withCelluloid like the seat, and can therefore not matchthe -color thereof.n

The obj ect of my invention is to overcome all the above describedinconveniences in the following manner:

rEhe various inconveniences of the different kinds of finishes for thehinges are eliminated, by eliminating the cause, namelyby hiding all themetal parts of which they are composed and which at present are exposed.The-inconvenience to clean the reartop of the flange of the bowl, whenhinges without an oifset are used, is eliminated, because said describedspot is freed of all obstruction; this is obtained by cutting from theseat that 05 portion of material which prevents easy'y cleaning, butleaving sufficient material at the rear end of'said seat, so as to formtwo suitable extensions to receive the hinge fixture com- Y binationpivotally mounted thereto, and said extensions longitudinally locatedbeyond the width of the iange in question, thus leaving the flange ofthe bowl clear all over. i

The inconvenience of limited choice of color and material to cover thehinge fixture is eliminated, as the member hiding the metal parts, whichalso cooperates i to form the hinge fixture, is so constructed that itcan be of suitable material to overcome the difi, culty of covering suchpiece with lCelluloid sheeting. This piece can be of hardwood, same asthe seat, or of any other suitable material, and in view of its shapeand construction it can, obviously, be covered to match the material andcolor of the seat.`

The cost is lowered because the number of metal parts is less, and thoseleft do'not need to be linished.

VThe quality is improved by the special construction of the hinge barwhich replaces the "L ordinary hinge fixture.v

rlhe entire construction is very substan- A tial, eliminating thepossibility of the hinges breaking, and the general lines are so neat 5that the cheap appearance of inexpensive seats is eliminated. 1 Theforegoing objects and advantages, t0-' gether with my subsequentfeatures, which a may be developed in the description, may be lou as Ybest appreciated from a description read in conjunction with thedrawings, in which:

Fig. 5 is a front view of the escutcheon carried by Fig. 4; f* Fig. 6shows another form of the escutch-v eon for bushings in Fig. 4.

Fig. 7 is a front view vof cutcheon.

Fig. 9 is a viewon lirico-6; 'Fig'. 10 is another view on line 5 5; Fig.l1 is an elevation side view of,another form of my invention, Fig. 12 isa baclrvi'ew partly in' section on line 4-4 of Fig. `11 carrying seat 9mounted thereto,

fIn all the lforms embodying my invention, the principal elements consist ofa. toilet seat, provided atvthe rear Aend' thereof withtwo'extensions, across' bar actingalso as an escutcheon, by concealingall of the 'metal parts and concurring to form the hinge'fixture withsaidfcrossfbar. `Said cross bar' can also be formed in-one piece withthe toilet bowl, thus eliminating `the two studs, which,

in combinationwith V`,the` pivots `form theV 1 hinge posts to attach theseat tofthe bowl.

. VReferringjto the drawings, and particularly to Figs. 2, 3, 8, 9, 10,11 and 12 a frag ment of a toilet bowl is indicated at 18.

Fig. l represents la plain view of. seatV 9, provided at the rear. endwithextensions 1Q, carrying bushings 11, held in rposition by screw 12.The concealing member '13 incooperation with pivots 14, studs 15 screwedthereto,for the hinge ixtureffastened to ange `16 of bowl J18 by nutsr19carryingal metal washer 20, a rubber washer 21-and rubber packing 32, toact as cushion, .as shown in Figs. 2,3, 9 and. 10. Member'13 is providedwith cavity 22 to put in position` pivots 14 carrying hole 23v for the`purpose of inserting a suitabletool to facilitate their removal in caseof need; saidpivots arehorizont-ally mounted in a suitable bore 24.'v'The concealing member- 13 is covered Vwith celluloidmaterial25,'saniecolor vand material as ,seat 9; it is understood that it canbe coveredwith different color and material, if desired. The bushing 11, asshown'in Fig. 4', is vprovided with a .perforation 28 for 'receiving thescrew 12 which serves to hold the` bushing securely within they recessformedl in one of the extensions on the seat; Wit-h thedoush--iV ings in`place the celluloid escutcheon 27 is `securely held Von the `exposediange of the same. In Fig. 6 a modified construction of the angular esva fragment ofY bushing is disclosed wherein the escutcheon comprises aring 29, the same being securely mounted on the flange portion of thebushing.

In Figs. 8, 9 and 10 there is disclosed a modified construction `of seat9, the same having extensions l0 and being hinged in a manner similar tothe preferred construction above described. This typeV of seat is openat the front and is mostly used in hotels,

schools, publicbuildngs and oilices and while not 'usually'fi'nishedinCelluloid can be so finished .if desired. The concealing bar 13 carriespivots 142 provided with apertures 23 and studs 15. In this modificationthe bushings a-re not flanged l'since this is not necessarywhenitheseatis'not Ycovered with material which can become detached by dampness orcontact withwater.

In the constructions described the seat is rigidly attached to the rearlflange of the bowl, provision, however, being made .to permit hingingof the seat with respect thereto. -v A feature ofthe invention is theconcealing of all metal parts, the particular arrangement inv addition`permitting ready detachment of the samefrom the bowl Vwhen desired.V'Ihe concealingbar having the cavity 22 maybe constructed of metal orof wood and. finished so as lto correspond with the finish ofthe seat,thecavity and the arrangeterial, preferably.leaid,to take care of anypossible imperfection in the bore 24 provided inthe concealing member.Extensions 31of the pivotsare fiat and are bent, after which lthe cavitylled with any kind of suitable hardening material whereby. the studs`are prevented from turning.

Although I haveshown several forms of my invention, I. am",l aware that,to those skilled in the art, other forms will readily suggestthemselves- Itis, therefore, my. intention` to include all such formsand modifications inthe nature of refinements of my invention that comewithin the scope of the specification and the essence of the invention.p
